Maybe I am reading this wrong but I am wondering who is posting while thinking SD out and about or at home. Obviously, very different.
I was taught (and I am outdated) that a heavy caliber was a poor SD especially in your own home or apartment. Buckshot lost more kill power after going thru 2 layers of sheetrock than a magnum.
Also, how many shots would one really get off in the middle of the night. Seems like I would be blind after 1 shot.
All that said, I have always counted on a 12 gauge with #4 buckshot as that is what the military recommended back in the day and if I only get one shot, I don't want to miss.
Just my 'old school thinking'. I am not claiming any of the above to be fact, just what I was taught /read and is my opinion.
Would like to know why others think a 357 or 44 mag is a good choice for the bedside table. (if that is what they do at home)
